update_mmu_cache

Name:The x86 doesn't have any external MMU info: the kernel page* tables contain all the necessary information.

Proto:static inline void update_mmu_cache(struct vm_area_struct *vma, unsigned long addr, pte_t *ptep)

Type:void

Parameter:

Type	Parameter	Name
struct vm_area_struct *	vma
unsigned long	addr
pte_t *	ptep

NULL

Name	Describe
follow_pfn_pte
insert_pfn
cow_user_page
wp_page_reuse	Handle write page faults for pages that can be reused in the current vma* This can happen either due to the mapping being with the VM_SHARED flag,* or due to us being the last reference standing to the page
wp_page_copy	Handle the case of a page which we actually need to copy to a new page.* Called with mmap_sem locked and the old page referenced, but* without the ptl held.* High level logic flow:* - Allocate a page, copy the content of the old page to the new one.
do_swap_page	We enter with non-exclusive mmap_sem (to exclude vma changes,* but allow concurrent faults), and pte mapped but not yet locked.* We return with pte unmapped and unlocked.* We return with the mmap_sem locked or unlocked in the same cases
do_anonymous_page	We enter with non-exclusive mmap_sem (to exclude vma changes,* but allow concurrent faults), and pte mapped but not yet locked.* We return with mmap_sem still held, but pte unmapped and unlocked.
alloc_set_pte	alloc_set_pte - setup new PTE entry for given page and add reverse page* mapping
do_numa_page
handle_pte_fault	These routines also need to handle stuff like marking pages dirty* and/or accessed for architectures that don't do it in hardware (most* RISC architectures)
set_huge_ptep_writable
hugetlb_fault
hugetlb_mcopy_atomic_pte	Used by userfaultfd UFFDIO_COPY. Based on mcopy_atomic_pte with* modifications for huge pages.
remove_migration_pte	Restore a potential migration pte to a working pte entry
mcopy_atomic_pte
mfill_zeropage_pte
